I was going to download vbulletin, and the following options were given. For ASO which options should I select?

What does the ASO servers use?

-----------------------------------------------------------------------------------------------
1) PHP File Extension: .php/php4 etc

2) CGI Shebang
This option will only be of use to you if your server runs PHP as a CGI rather than as a web server module. If your server runs PHP as a CGI and requires a shebang (such as #!/usr/bin/php) then you can enter the required text here and it will automatically be inserted into whichever PHP files in vBulletin require its use.

Thanks

.php

we don't require a bang.

Thanks.

She bangs! She bangs! Oh baby, she moves! She moves!

Thanks for the caution. Tad to late.

WOW here it is what 18mo later and I'm doing the exact same thing, d/l'ing Vbulletin and I come across the very same questions. Thanxx for asking when you did! And Thanxx to ASO for leaving this post in place!
